Working days

Hello!

We have been issued with some holidays which can be transferred to another (working) days.

Let me explain with an example.
In Russia we have a holiday on 23 Feb. So we have 3 days holiday: Sunday(21), Monday(22) and Tuesday(23). But in this case we should work on Saturday for Monday. And there is no way to transfer days or make weekend days working.

So please add a feature like a "close days" but with reverse functionality.
